Read my lips - mercy is for wimps! There's a reason "oppose" rhymes with "dispose"...If they get in your way, kill them!
Ultimate + Apocalypse Battles
Imperial Elite Forces
凶Mega Armor (w/Sergeant and Imperial Elite)
HP: Mega Armor: 45,000 - Sergeant: 18,000 - Imperial Elite: 28,000
Target Score:
- Defeat the boss with 3 or more heroes not KO'ed.
Weak: Mega Armor + Sergeant: Lightning, Water - Imperial Elite: Poison
Absorb: None
Resist: None
Null: Earth
Status Vulnerabilities: None
Notes: Mega Armor can do both magical and physical damage, and also carries gravity attacks. The support soldiers are all physical.
Be cautious of Last Stand as the Armor and Imperial Elite can Sap. The Sergeant can also silence.
There are three total waves of enemies.
1: Mega Armor x1, Sergeant x2
2: Mega Armor x1, Imperial Elite x2
3: Mega Armor x3
Tritoch, meet Enemies. Enemies, Tritoch.
Remember that gravity damage from earlier? It is a counter for black/white magic. Abuse Tritoch and get mitigation up quick. Not a difficult fight.
Phoenix Cave +
凶Red Dragon
HP: 350,000
Target Score:
- Defeat the Red Dragon with at least 3 characters not KO'ed.
Weak: Ice, Water
Absorbs: Fire
Resists: None
Null: None
Vulnerabilities: None
Notes: Token physical attack, everything else is magical (and most of it is fire element!).
This is a straightforward fight that may be over pretty quick. There is a piercing magical hit to worry about, but thats why you bring fire resist accessories. Just don't use Reflect, as you'll get a Dispel to the face as an instant retaliation.
Acolyte Archive: Plenty of strong units with access to ice in 6. Water not to much, but that is standard for FFRK.
Mog's BSB can be very utilitarian here, offering a backup instant heal, hastega, mag boost for Terra and Strago, and a magic breakdown. Relm and Setzer/Mog would also generally be needed for heals and support.
Otherwise you're not really required to bring anyone for a specific mechanic, so go nuts.
Dullahan (Apoc +)
滅Dullahan
HP: 480,000
Target Score:
- Defeat Dullahan with 2 or more heroes not KO'ed.
Weak: Fire
Absorbs: Ice
Resist: None
Null: None
Vulnerabilities: None
Notes: Really, this would have fit better for the CM. Terra and Locke can rip this guy apart faster than you can skip pulling on B1.
Mixed attacks with a preference to magical. And like the other times fighting him, Stop is a thing and Dullahan's Mnd is 300. Mind Breakdown/Affliction Break may be better options over Stop resist accessories, because his piercing attack is ice element and it can hurt even with mitigation. A status blink works just as well.
Finally, Dullahan has a 15-25% chance (based on phase) to counter any attack with a weak physical counter.
Fiend (Apoc ++)
滅Fiend
HP: 625,000
Target Score:
- Defeat Fiend with 2 or more heroes not KO'ed.
Weak: Holy
Absorbs: Ice
Resist: None
Null: None
Vulnerabilities: None
Notes: Yes, this is a full Holy weak (200%) Apoc + fight.
Mixed attacks, and carries a slightly upgraded 3x target Stop but at a weaker success chance. Also like Dullahan, his elemental moves are ice based.
The main worry point is Fiendish Rage and its Very Weak (40%) upgrade to Ultimate Fiendish Rage. Though not piercing, the initial version still hurts and is not blink-able. The second version isn't piercing either, but carries a Dispel effect and a potency of 1200%.
Again, 200% weakness to holy.
Acolyte Archive:
Celes can use Assault Saber.
Leo can use Assault Saber.
200% holy weakness.
If you have Setzer's airship pimped out, he is a better option than Mog here for the stacking atk debuffs. The Stop is a slight worry, but not as accurate as Dullahan and Affliction Break (again, Setzer) can mitigate it nearly entirely.
With the holy weakness, you should be able to dig in reliably with a number of options in-realm, Celes and Leo especially. Sadly, Celes won't be able to take advantage of her Spellblade affinity with holy, but Leo can despite his earth knight focus.
Bank the 2mil gil.
